Luning

Geologic setting:
Geothermal features:
Prior to NBMG sampling, the aquifer geochemistry and geothermometry was unknown between
Luning and Mina, northeast Soda Springs Valley. The Luning water tank well was sampled at its
basal outflow point (19.7°C). Geothermometer values are low, at 46.1°C (Na-Ca-K-Mg) and 67.5°C
(chalcedony). Location coordinates are 118.18023 W, 38.50221 N (NAD83). A handpump at the
Luning rest stop was tested for pH, temperature, and conductivity, but not sampled (temperature was
only 16.6°C). The water was clear and unscented.
East of Mina, the Southern Pacific Spring flows from a bedded rhyolite hillside and continues
downslope 400m (17.4°C). The water is clear and unscented, and small leafy plants grow within the
water. Geothermometer values are low-to-moderate, at 47.9°C (Na-Ca-K-Mg) and 89.7°C
(chalcedony). Location coordinates are 118.06186 W, 38.42167 N (NAD83). The Rassler Wells W01 and W-02 are housed in small chemical storage sheds containing calcium hypochlorite. Outflow
tubes have thick calcium deposits inside, and would not be suitable for sampling on account of
chemical contamination.
